Cumberbatch's star has gone supernova since Sherlock bowed two years ago (our verdict then: he had a name and cheekbones bound for glory), becoming especially well-known to science fiction and fantasy aficionados.

Sherlock has met with positive acclaim, huge audience numbers and found a diverse following. Its fandom, ever flourishing, is one of the most devotedly productive on the internet.

We have a range of queries we'd love to lob at anyone involved in the all-around excellent production that is Sherlock, including but not limited to Mr. Cumberbatch's feelings on otters, but we want to hear what you want to know.

Please be careful to avoid revealing second-season spoilers to those who have yet to start their trip into Sherlock's delightfully dark and twisty world.
